Making portable GridStack 4.1 (Voltaire OFED) drivers.

Remove previously installed IB rpms if there. To do this;
rpm -e kernel-ib-1.0-1 \
dapl-1.2.0-1.x86_64 \
libmthca-1.0.2-1.x86_64 \
libsdp-0.9.0-1.x86_64 \
libibverbs-1.0.3-1.x86_64 \

And remove by hand all of "ib_" modules with "rmmod modulename" command

*** If you installed previously OFED IB with same package you can run ./uninstall.sh
script which is included GridStack-4.1.5_9.tgz package instead above steps.
This script does same and plus things automaticaly so you can prefer.

1. First optain Gridstack source code from Voltaire.
And then;
mkdir /home/setup
cp GridStack-4.1.5_9.tgz /home/setup
cd /home/setup
tar -zxvf GridStack-4.1.5_9.tgz
all of files will be in "/home/setup/GridStack-4.1.5_9"

cd GridStack-4.1.5_9

2. Install the GridStack drivers

./install.sh --make-bin-package

This process takes about 30 minutes.
time to coffee or tea but not cigarette...
INFO: wrote ib0 configuration to /etc/sysconfig/network-scripts/ifcfg-ib0

Installation finished
Please logout from the shell and login again in order to update your PATH environment variable

3. Finishing the driver settings
Firts edit ip settings for IB
Just edit "/etc/sysconfig/network-scripts/ifcfg-ib0" like below;


save and reboot the system.

4. GridStack installation puts a init.d service on the system startup.
After the bootup process you must see ib0 device on ifconfig command and
LEDs of HCA cards must be on or blinking state. Check this...

After the reboot check the state of connection by ifconfig

If you see similar of above message you won. Ping the neighbors IP addres if avaible there;
PING ( 56(84) bytes of data.
64 bytes from icmp_seq=0 ttl=64 time=0.094 ms
64 bytes from icmp_seq=1 ttl=64 time=0.057 ms
64 bytes from icmp_seq=2 ttl=64 time=0.064 ms
64 bytes from icmp_seq=3 ttl=64 time=0.056 ms

If you does not see ib0 or cannot ping gridstack service may not be started.
Start by manualy: /etc/init.d/gridstack start

If everything ok you can make an image of this system for
central deploying mechanism like tftp.

6. Installing new compiled GridStack driver to identical machines.
It is so easy. After the GridStack compilation process a new bz2 file and
their md5 checksum are created automaticaly. You can find these two files under the
upper level of source folder. On our example two files wait for your attn in there;

ls -al /home/setup
-rw-r--r--   1 root root       88 Nov 23 19:11 GridStack-4.1.5_9-rhas-k2.6.9-42.ELsmp-x86_64.md5sum
-rw-r--r--   1 root root 43570798 Nov 23 19:11 GridStack-4.1.5_9-rhas-k2.6.9-42.ELsmp-x86_64.tar.bz2

Copy this two files to all of the IB hosts which you want to plan GridStack installation.
Opposite to previous steps this installation not takes too many minutes.
Just copy files to new machine by scp;

cd /home/setup
scp GridStack-4.1.5_9-rhas-k2.6.9-42.ELsmp-x86_64 root@

Change to target machine console and type those commands;

cd /home
first check-out the binary equality of bz2 file
md5sum -c GridStack-4.1.5_9-rhas-k2.6.9-42.ELsmp-x86_64.md5sum
GridStack-4.1.5_9-rhas-k2.6.9-42.ELsmp-x86_64.tar.bz2: OK

if you see OK sign type this;
tar -jxvf GridStack-4.1.5_9-rhas-k2.6.9-42.ELsmp-x86_64.tar.bz2

A folder which is called "GridStack-4.1.5_9-rhas-k2.6.9-42.ELsmp-x86_64" will be created.
cd GridStack-4.1.5_9-rhas-k2.6.9-42.ELsmp-x86_64/

GridStack binary rpms will be install automaticaly.
Make ifcfg-ib0 setting like above, reboot and check for IP connectivity.

7. As a bonus advice;
After the GridStack installation there is lots of ib diagnostics tools avaible under the
/usr/local/ofed/bin directory. So for example issuing the ./ibv_devinfo give an brief
and usefull informations about HCA connectivity, board model, FW level and ... etc

Here ise sample output for my machine;

                        sm_lid:                 29
                        port_lid:               75
                        port_lmc:               0x00

                port:   2
                        state:                  PORT_ACTIVE (4)
                        max_mtu:                2048 (4)
                        active_mtu:             2048 (4)
                        sm_lid:                 29
                        port_lid:               261
                        port_lmc:               0x00

    You are about to replace current PSID in the image file - "VLT0040010001" with a different PSID - "VLT0040010001".
    Note: It is highly recommended not to change the image PSID.

Where /usr/local/bin/ib-burn is a realy BASH script
this is another deep way to burn HCA card FW

lspci -n | grep -i "15b3:6278" | awk '{print $1}'
if you see "13:00.0" as output type this;

mstflint -d 13:00.0 -i /usr/voltaire/fw/HCA400Ex-D-25208-4_7_6.img -vsd1 "" -psid HP_0060000001 -y burn > /root/hca-fw-ugr.log
This command does not prompt for Yes.

For checking FW on the flash type this;
mstflint -d 13:00.0 q

SFS 2.2-1 Client Upgrade witch GridStack 4.x

SFS is the Hewlett Packard's Parallel File Systems which is based on the open source Lustre file system.
As an acronym SFS stands for Scalable File Share. HP company also has SFS20 disk enclosures must be not conflict to this software.

Here we are upgrading the client packages (rpms) to new level.
Enter to /home/sfs-iso-loop/client_enabler and run;

./build_SFS_client.sh --no_infiniband --config --allow_root \

cd /home/sfs-iso-loop/client_enabler/output/RPMS/x86_64

rpm -ivh kernel-smp-devel-2.6.9-34.0.2.EL_SFS2.2_1.x86_64.rpm

change /boot/grub/menu.lst to boot from this new kernel.

Reboot the machine and showtime ...
